Crucial 16 GB DDR5-6400 laptop memory

This 16 GB DDR5 CSODIMM module runs at 6,400 MT/s from the moment it is installed. It targets laptop owners who want a straightforward speed increase for everyday workloads and light content creation without manual tuning.

On-board clock driver stabilises timing

The module integrates a clock driver that keeps signal integrity tight at the rated frequency. This hardware-level feature supports consistent throughput for large file transfers and helps the memory subsystem maintain its refresh cadence under sustained load.

Check DDR5 slot and 6400 MT/s support

Verify that your laptop accepts DDR5 CSODIMMs and that its memory controller can operate at 6,400 MT/s. Systems limited to DDR4 or to lower JEDEC speeds will not be able to use this module at its rated performance.

Questions about this item

Will the on-module clock driver on this CSODIMM need replacement over time?

The clock driver is a permanent part of the module and has no separate service schedule.

Does CAS latency 52 become the bottleneck during long rendering sessions?

Latency stays at CL52 regardless of workload duration; it does not increase with sustained use.

How much extra heat does the clock driver add when the laptop runs all day?

The clock driver operates within standard DDR5 thermal limits and does not raise module temperature beyond normal levels.
